Neoprene (synthetic rubber) is a polymer of

Options

A. Propene
B. Vinyl chloride
C. Chloroprene
D. Butadiene

Explanation

To determine the polymer of neoprene, we can follow these steps:

### Step 1: Identify the monomer
Neoprene is a type of synthetic rubber. To find out what neoprene is a polymer of, we need to identify its monomer. The monomer for neoprene is chloroprene.

### Step 2: Write the structure of chloroprene
Chloroprene has the following structure:
- It contains a double bond between two carbon atoms and a chlorine atom attached to one of the carbon atoms.
- The chemical formula for chloroprene is CH2=CCl-CH=CH2.

### Step 3: Understand the polymerization process
The polymerization of chloroprene involves the linking of multiple chloroprene monomers through a process called addition polymerization. During this process, the double bonds in chloroprene open up and bond with other chloroprene molecules to form long chains.

### Step 4: Write the structure of neoprene
The resulting polymer, neoprene, is a long chain of repeating chloroprene units. The general structure can be represented as:
- [-CH2-C(Cl)=CH-CH2-]n, where "n" indicates the number of repeating units.

### Conclusion
Thus, neoprene is a polymer of chloroprene.
